<span>saturated fatty acids don't have double bonds, but unsaturated do. Because the sat fat acids do not have these double bonds they pack together more easily, and have stronger intermolecular forces,eg .van der waals between them. so there generally solid. Whereas unsat fat acids have double bonds, therefore they have kinks and twists in the chains, less strong van der waals force between them and so liquid state. this is at room temp. </span>
<span>The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reactionmust equal the mass of the reactants.
i hope this helps:)</span>
Answer:
Also called superposition. When overlapping waves produce a wave with an amplitude that is the sum of the individual waves. When overlapping waves produce a wave with an amplitude that is less than the sum of the individual waves.
Explanation:
Scientists measure mass with a balance, such as a triple beam balance
So A is true
Answer:
1:1
Explanation:
The ratio of metal cationic atom to non-metal anionic atom in the compound is 1:1.
This is an ionic compound.
- This is because metal cationic atom has two valence electrons.
- Non-metal anionic oxygen has six valence electrons
- Calcium loses two of its valence electrons to be isoelectronic with Ar and this confers a stable configuration to it.
- Non-metal oxygen atom accepts the electrons and adds 2 to its 6 electrons to become isoelectronic with neon.
- So, 1 metal cationic atom combines with 1 non-metal anionic atom to form the compound.
